Fig. 4: Performance of proteins measured using Olink and SomaScan platforms for prediction of incident IHD.

Analyses were conducted for 1694 matched proteins among 3976 participants, including 1951 IHD cases and 2025 subcohort participants. Conventional risk factors for cardiovascular disease included age, sex, smoking, type 2 diabetes, systolic blood pressure, and waist circumference. Protein measurements for 1694 one-to-one matched proteins from both platforms or from one platform were used to build the models. Data are presented as estimated C-statistics, with error bars indicating 95% confidence intervals. NRI were computed with a decile-based method.
